The search for superconductors with high values of the critical temperature has started shortly after the first observation of the phenomenon in 1911. At present, there are several paths towards reaching this goal. Here we focus on the direction based on observing high temperature superconducting state in some metallic nanoclusters. The macroscopic high Tc superconducting current can be provided by the Josephson tunneling between such clusters.

基于纳米的约瑟夫森隧道网络和高温超导性

在1911年首次观察到这种现象后不久，就开始了寻找具有临界温度高值的超导体的工作。目前，有多种途径可以实现这一目标。在这里，我们重点研究基于观察某些金属纳米团簇中的高温超导状态的方向。宏观的高Tc超导电流可以通过此类簇之间的约瑟夫森隧穿来提供。
